Johnson appeared in two episodes in The Twilight Zone. He attempted to prevent the assassination of Abraham Lincoln in “Back There”. He appeared as a college professor in the episode, “Execution”. The plot of both episodes involved time travel from the 20th to the 19th centuries.

You beat me to it. And you of course got both correct. Did you actually remember him being in these 2? I initially forgot the one about the execution.
